Clamp employs six (possibly seven) metaprogramming functionalities in Python/Jython:

1. Metaclass support, which required unifying Java types (rooted by java.lang.Class) and Python new-style classes (rooted by type). This then enable the metaclass to build the desired class shape. It can do the following: constant type inference; construction of getters/setters; etc.

2. Brand new, __proxymaker__ allows for a CustomMaker to intercept
